The Steyr HS .50 is a single-shotbolt-action rifle. It has no built-in magazine, and each round has to be loaded directly into the ejection port and is pushed into the chamber by the bolt. The fluted barrel is cold hammer-forged and has an effective range of up to 1,500 m. It has an adjustable bipod, a muzzle brake that reduces recoil significantly, and a Picatinny rail for the installation of various optics.
The original Steyr HS-50 was designed by Heinrich Fortmeier, on behalf of Steyr Arms.
Variants

AM-50 Sayyad
Iran produces an unlicensed copy under the name AM-50 Sayyad.[4] The AM-50 has been in production since 2008 and has been widely exported.[5] Because of its wide exports, AM-50 rifles have also been supplied to or captured by groups opposed to Iran, such as Syrian rebels.[3] The AM-50 reportedly has much worse fit and finish than the original Steyr HS .50.[5]
Golan S-01
In June 2018, media organizations affiliated with the Syrian government[6] reported that Syria had begun producing an unlicensed variant of the rifle, dubbed the Golan S-01, in reference to the Golan Heights. Its first prototype was issued in 2015. Unlike the original HS .50, the Golan S-01 fires the Soviet 12.7×108mm anti-materiel rifle cartridge.[7] It is slightly heavier than the HS.50, weighing in at 13.5 kg and has an effective firing range of 1,600 meters, a 100-meter improvement over the previous generation of anti-materiel rifles used by the Syrian Army. It is also 100 mm longer than the HS .50, measuring in at 1,470mm total length.[8] It is manufactured by Golan Rifle Plant. In 2023, the SSRC has upgraded the Syrian produced Golan S-01 AMR. New model Golan S-01 Mk.2 was introduced with a new stock, box magazine, and scope.[7]
Al-Ghoul
Named after the Hamas engineer and senior operative Adnan al-Ghoul, this is a Palestinian-made sniper used by the Al-Qassam Brigades. One of the world’s longest sniper rifles with a length of 1.5 meters, it differs from the typical model as it uses 14.5mm and 12.7mm caliber ammunition. The rifle has a range of 2 km.[9] Hamas first used this rifle in the 2014 Gaza war. The group also stated that these rifles are “evidence of the distinction of its military industries”.[10]
